This is a Continuation-in-Part of U.S. patent application Ser. No. 12/572,749, filed Oct. 2, 2009.

BACKGROUND OF THE INVENTION

1. Technical Field

This invention generally relates to pool equipment and installation of the same. More particularly, the invention relates to a device for securing a pool fixture and pool liner together. Specifically, the invention relates to a sealing member that retains the pool liner between an inner and outer frame member in such a manner that the liner is not pierced.

2. Background Information

There are many in-ground swimming pools sold and used in North American that use a vinyl liner type of construction approach versus a traditional concrete molded system. The vinyl liners in these pools are typically in the range of 0.017″ to 0.03″ thick and generally have to be changed after around ten years of use. Additionally, a variety of plastic or fiberglass fixtures such as stairs, skimmers, underwater lights, speakers, drains and filling ports have to be installed and sealed to the new vinyl liner once it has been installed in the pool.

Installing a new liner is a time-consuming task that must be undertaken with care in order not to puncture the liner. The first step involves removal of the old liner, followed by cleanup and repair of the surface that is to support the new liner. If the pool includes plastic stairs, the installer must construct a bridge across the top of the stairs. The new liner is then placed on the bottom of the pool and the outer perimeter of the liner is systematically zipped into a specially designed track mounted around the uppermost lip of the pool. During this process, the liner is drawn up against the bridge across the stairs so that a portion of the liner spans the opening to the stairs. A vacuum hose is positioned between the liner and the sidewall of the pool in order to evacuate the air between the liner and the surface supporting the same. This process also aids in smoothing out any wrinkles in the liner. The installer then starts filling the pool with water and stops when the water reaches a depth of about six inches in the shallow end.

At this point, the installer needs to install the various pool fixtures and provide access to the stairs, if present. This is accomplished by installing an outer frame member and a rubber gasket in the appropriate regions of the pool to seal the liner surrounding the fixture or the stairs. The outer frame member and gasket are designed to be engaged with the fixture and are shaped appropriately. Each of the gasket and outer frame member are provided with pre-drilled or pre-formed apertures therein for the insertion of fasteners into aligned apertures in the fixture. The gasket is positioned in abutting contact with the exterior surface of that portion of the liner disposed over the apertures in the fixture. The outer frame member is positioned in abutting contact with the gasket and then a number of fasteners are inserted through the aligned apertures in the outer frame member, the gasket and the fixture. This, of course, results in perforation of the liner at each and every location that a fastener is used. A typical stair system, for example, may require as many as eighty 1 1/2″ screws to secure the liner around the stairs. The screws typically are positioned every three to four inches along the length of the face place. When all of the screws are tightly fixed into place, the outer frame member essentially retains the liner and gasket to the fixture and thereby seals off the liner around the same. The installer then cuts away that portion of the liner that is blocking access to the fixture.

This method of installation is problematic for a number of reasons. Firstly, it is a very time consuming and labor intensive because the installer has to physically install each and every fastener. This can be quite difficult as it may require the installer to lie on their stomach and reach downwardly into the pool to screw in each and every fastener from an awkward angle. This time consuming and labor intensive activity forms part of the cost of installation of the liner. Consequently, the longer it takes to accomplish this task, the more it bites into the profit for the job. Secondly, since this installation method involves repeated puncturing of the liner, this type of installation may lead to leaking problems if the installer is less skilled.

One of the regions of vinyl pool covers that is particularly problematic to install is the region surrounding stairs. There is a tendency for the pool cover to wrinkle and fold, especially around the corners at either end of the bottom step. Presently known installation assemblies can damage or even cut the pool cover in these corner regions, particularly if these assemblies include mitered corner pieces.

U.S. Pat. No. 4,920,714 to Sease discloses a system for mounting flexible coverings on support surfaces. The system includes prefabricated contour pieces for securing flexible coverings in corner type regions. The patent discloses a lower molding element which is secured to the support surface and an upper mounting element which interlockingly engages the lower molding element. The edge of the flexible fabric is inserted into a channel structure in the upper surface of the upper mounting element and the channel structure is then inserted into a gap between upstanding retaining walls in the lower molding element. The channel structure is pinched closed by the retaining walls and this, combined with teeth in the channel structure; hold the edge of the fabric. The patent discloses that the upper mounting element may be prefabricated as a single contoured piece which has two or more legs that are interconnected to each other at particular desired angles. These single contoured pieces include a right-angled mounting element and a curved mounting element which may be used to form a right angled corner. The two lower molding elements mounted to the support surface are terminated a distance away from the corner so that a gap is defined between them. The single piece contoured upper mounting element is used to span this gap and to actually form the corner. The edge of the flexible fabric is then inserted into the channel structure of the contoured upper mounting element and any excess fabric is pushed into slits that radiate outwardly from the channel structure in order to remove puckers and wrinkles from the fabric. While this device is suitable for mounting wall coverings and the like it would not be suitable for securing pool liners. Inserting the edge of a pool liner into the small channel structure and pushing the excess regions of liner into the slits would be difficult considering the thickness of the liner. Additionally, the gripping teeth which retain the fabric within the channel structure could potentially puncture or damage the liner, causing it to leak. The side edges of the upper surface which form the slits could also cut the liner as it is pushed into the same. The presence of the gap beneath the upper mounting element is also potentially problematic in that it provides a zone in which the liner would not be hugging either the pool wall or the mounting assembly. Consequently, any accidental contact with the liner in this zone could lead to that region of the liner being stretched, wrinkled or even punctured.

There is therefore a need in the art for an improved method and apparatus for securing and sealing a vinyl pool liner to a pool fixture, and more specifically for an improved method and apparatus for securing and sealing a vinyl pool liner around a pool stair system.

SUMMARY OF THE INVENTION

The present invention is a device used to seal a pool fixture and a vinyl pool liner together and a method of using the same. The sealing member includes an inner frame member which is mounted on the pool fixture or is integrally molded as part of the fixture. The outer frame is designed to interlockingly engage the inner frame member retaining the pool liner between the inner and outer frames. One of the inner and outer frame members includes a channel and the other includes a complementary projection that is receivable in the channel. A bead of sealing material is provided one of in the channel and on the projection. When the inner and outer frame members are engaged, the liner is pushed into the channel by the projection and is maintained in contact with the sealing material. The outer frame member is easily removed from the inner frame member to allow for periodic replacement of the pool liner.

A second embodiment of the invention includes a sealing member for securing a vinyl pool liner to a stair system and comprising a first sealing component which is secured along a side wall defining the stairs; a bottom sealing component secured to the wall beneath the stairs and a corner assembly disposed between the two. All of the first and bottom sealing components and the corner assembly include an inner frame member and an outer frame member which are configured to snap-fittingly engage each other and clamp a portion of the liner between them. The corner assembly is curved and a cover is engaged over the outer frame member of the corner assembly to prevent accidental disengagement thereof. The cover extends for a distance along each of the first and bottom sealing components. The outer frame member defines a plurality of apertures in its upper surface which are configured to receive studs extending outwardly from the cover.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-7, there is shown a first embodiment of a sealing member for securing vinyl pool liners to pool fixtures in accordance with the present invention and generally indicated at 10. In particular, this embodiment of the sealing member 10 is designed for use with larger pool fixtures such as stair systems 12 (FIG. 3).

Sealing member 10 comprises an inner frame member 14 and an outer frame member 16 that are matingly engageable with each other as illustrated in FIG. 2. Inner frame member 14 and outer frame member 16 are both substantially straight, elongated members that have a length “L” and a width “W”. Preferably, inner and outer frame members 14, 16 are manufactured from a substantially rigid plastic or fiberglass and are substantially non-flexing.

Inner member 14 is generally U-shaped in cross-section and includes a bottom wall 18 with two side walls 20, 22 extend upwardly and outwardly therefrom and defining a channel 24 thereinbetween. Side wall 20 has a first surface 20 a that is disposed at an angle other than 90° relative to bottom wall 18. Side wall 20 further includes a second surface 20 b disposed substantially parallel to bottom wall 18. A beveled surface 20 c connects first and second surfaces 20 a, 20 b. A region of side wall 20 extends inwardly for a distance over bottom wall 18 thereby forming a lip 26 that is separated from bottom wall 18 by a groove 28 that is in communication with channel 24. Side wall 22 has a first surface 22 a that is disposed substantially at right angles to bottom wall 18, and a second surface 22 b disposed substantially parallel to bottom wall 18 and at right angles to first surface 22 a. A region of side wall 22 extends inwardly for a distance over bottom wall 18 thereby forming a lip 30 that is separated from bottom wall 18 by a groove 34 that is in communication with channel 24. Lip 26 and lip 30 extend toward each other and are separated by a gap that has a width “W1”. It should be noted that lips 26 and 30 each have a beveled surface 26 a, 30 a that enables it to be easier to insert portions of the outer frame member 16 through this gap and into channel 24.

Outer frame member 16 comprises a generally L-shaped member that interlocking engages with inner frame member 14. The L-shaped member includes a back 36 having an inner surface 36 a and an outer surface 36 b. A first flange 38 projects outwardly away from back 36 and at an angle substantially around 90° relative to outer surface 36 b. First flange 38 runs substantially the entire length “L” of back 36. When outer frame member 16 is interlocking engaged with inner frame member 14, flange 38 extends for almost the entire depth of side wall 22 from second surface 22 b to bottom wall 18 of inner frame member 14. Flange 38 includes an outer surface 38 a, an inner surface 38 b and a tip 38 c. The transition from inner surface 38 b to tip 38 c preferably is gently rounded. Inner surface 38 b is disposed generally at right angles to outer surface 36 b of back 36. Outer surface 38 a preferably is disposed at an angle other than 90° to outer surface 36 b.

A second flange 40 extends outwardly from back 36 and runs for substantially the entire length “L” thereof. Second flange 40 includes an outer surface 40 a and an inner surface 40 b that are substantially parallel to each other and are connected together by a tip 40 c. Each of the inner and outer surfaces 40 b, 40 a is disposed at an angle other than 90° relative to outer surface 36 b of back 36. Preferably, first and second flanges 38, 40 flare away from each other. Second flange 40 does not extend outwardly from back 36 for as great a distance as does first flange 38. Consequently, tip 40 c of second flange 40 is disposed closer to outer surface 36 b than is tip 38 c of first flange 38.

Outer frame member 16 further includes a pair of legs 42, 44 disposed between first and second flanges 38, 40. Legs 42 and 44 are spaced a distance laterally apart from each other and preferably extend longitudinally from one end of outer frame member to the other. It will, of course, be understood, that a plurality of individual leg members could instead be provided at intervals along the length of outer frame member 16.

In accordance with the present invention, leg 42 has an inner surface 42 a and an outer surface 42 b and includes a lip 42 c that extends outwardly from outer surface 42 b. Leg 44 has an inner surface 44 a, an outer surface 44 b and includes a lip 44 c that extends outwardly from outer surface 44 b.

Lips 42 c and 44 c are generally coplanar and extend in opposite directions from each other. Each of lips 42 c and 44 c are of a size that is sufficiently small enough to permit them to be received into one of grooves 28 and 34 of inner frame member 14.

The inner surface 36 a of outer frame member 16 is not a substantially flat surface. Instead, inner surface 36 a includes notches and recessed areas 48. Each notch 46 is adjacent the outer surface of one of the legs 42, 44 and recessed areas 48 are defined between legs 42, 44 and spaced a distance from each other. Notches 46 allow legs 42, 44 to flex to a certain degree when outer frame member 16 is engaged with inner frame member 14 as will be hereinafter described.

FIG. 2 illustrates how the inner frame member 14 and outer frame member 16 are interlockingly engageable with each other. It should be noted that the angle of inner surface 40 b of second flange 40 and beveled surface 20 c on side wall 20 are substantially identical. When inner and outer frame members 14, 16 are engaged, inner surface 40 b and beveled surface 20 c are disposed adjacent each other and are oriented substantially parallel to each other. Furthermore, side wall 20, including lip 26 is sized to be received between second flange 40 and leg 42 and side wall 22 is sized to be received between first flange 38 and leg 44. Lips 42 c and 44 c on legs 42, 44 are received in grooves 28 and 34 respectively, thereby interlocking engaging inner and outer frame member 14, 16 together in such a manner that they cannot be accidentally separated from each other. Inner frame member 14 and outer frame member 16 are snap fitted together and are retained in place by friction.

It should be noted, however, that while inner and outer frame members 14, 16 are interlocking engaged, the fit between inner and outer frame members 14, 16 is fairly loose. By this it is meant that there is some vertical play between inner and outer frame members 14, 16 as is indicated by arrow A-A1 in FIG. 2. There is also some horizontal play between inner and outer frame members 14, 16 as is indicated by arrow B-B1 in FIG. 2. This loose fit between inner and outer frame members 14, 16 causes a gap 52 to be formed between the inner and outer frame members 14, 16 when they are engaged and it is into this gap 52 that the vinyl pool liner 54 is received as will be hereinafter described.

FIGS. 3-7 show the sealing member 10 in accordance with the present invention being used to secure vinyl pool liner 54 to a stair system 12. In this instance, stair system 12 defines a recessed area 56 sized and shaped to received inner frame member 14 therein. A backer board 19 is received on a back surface of stair system 12 proximate the region where inner frame member 14 will be engaged. As shown in FIG. 4, the wall that defines recessed area 56 preferably includes a surface 12 a that is complementary in shape and angle to first surface 20 a of inner frame member 14. This enables the installer to quickly and easily orient the outer frame member 16 for interlocking engagement with inner frame member 14. If outer frame member 16 is oriented incorrectly for engagement with inner frame member 14, the second flange 40 on outer frame member 40 will contact surface 12 a and essentially prevent outer frame member 16 from being pushed into channel 24 in inner frame member 14. This ensures that all components are oriented correctly so that the best seal possible is obtained between sealing member 10 and pool liner 54.

As shown in FIG. 4, inner frame member 14 has an interior surface 15 a adapted to abut gasket 58 and an exterior surface adapted to abut an interior surface 54 a of liner 54. Outer frame member 16 has an interior surface 17 a and an exterior surface 17 b. Interior surface 17 a is adapted to abut an exterior surface 54 b of liner 54.

The installer positions a backer board 19 adjacent a rear surface of stair system 12. A gasket 58 is then positioned between interior surface 15 a of inner frame member 14 and the recessed area 56 on stair system 12. A plurality of fasteners 60 are used at spaced at intervals along the length of inner frame member 14 to secure inner frame member 14 to stair system 12 and backer board 19. It will be understood that instead of fasteners 60, inner frame member 14 may be glued into recessed area 56 or inner frame member 14 and gasket 58 may be glued to each other and into recessed area 56. FIG. 5 shows that a bead of calking 62 or other type of sealant is introduced into channel 24 of inner frame member 14. The bead of calking 62 preferably extends longitudinally for the entire length of inner frame member 14. The installer then installs the liner as has been described in the background section of this application. Essentially, the interior surface 54 a of the liner 54 is placed in abutting contact with the pool walls and floor. When the installer reaches the region of the pool in which stair system 12 is located, the interior surface 54 a of liner 54 is positioned over the exterior surface 15 b of the previously installed inner frame member 14. For the sake of clarity, only the small portion of liner 54 which overlays inner frame member 14 is shown in FIG. 3. It will be understood, however, that liner 54 extends across the entire access opening to stair system 12 and around the entire perimeter of the pool.

Once the air has been evacuated from between the interior surface 54 a of liner 54 and the pool walls and floor, the installer engages the outer frame member 16 with inner frame member 14. This is accomplished by contacting the exterior surface 54 b of liner 54 with the interior surface 17 a of outer frame member 16. Most specifically, the legs 42, 44 of outer frame member 16 are placed in contact with the exterior surface 54 b of liner 54 and the installer pushes the outer frame member 16 inwardly toward inner frame member 14. This movement causes legs 42, 44 of outer frame member 16 to enter into channel 24 of inner frame member 14. As legs 42, 44 move into channel 24, they force a portion of liner 54 into channel 24 and into contact with the bead of calking 62. The installer pushes outer frame member 16 inwardly toward inner frame member 14 until tips 42 c, 44 c of legs 42, 44 enter grooves 28, 34. The inwardly moving legs 42, 44 and liner 54 tend to force caulking 62 to spread throughout channel 24 and into grooves 28, 34. The caulking is trapped between liner 54 and inner frame member 14, thus sealing off fluid access to an interior surface of liner 54. Consequently, neither air nor water can cross the barrier formed by sealing member 10 with liner 54. Furthermore, liner 54 is tightly retained in the gap 52 between inner and outer frame members 14, 16. Thus, the outer frame member rigidly maintains the pool liner in the channel 24 and in contact with the calking 62. The inner and outer frame members retain the pool liner therebetween in such a manner that the liner is not pierced.

After the installer has secured liner 54 along the sides 12 a, 12 b and the bottom 12 c of stair system 12, he takes a cutting tool and cuts away that portion of the liner that spans the opening between sides 12 a, 12 b.

Referring to FIGS. 8-11, there is shown a second embodiment of a sealing member in accordance with the present invention and generally indicated at 110. All of the various components of the sealing member 110 are substantially identical to the components of sealing member 10 with the exception of the outer frame member 116. Consequently, sealing member 110 includes an inner frame member 114 that is secured by screws 160 into a recess 156 to a fixture, such as a stair system 112, and to a backer board 119 associated therewith. In the first embodiment of the invention, a single screw 60 was disposed within channel 24. In this present embodiment, a pair of spaced apart screws is disposed a spaced distance laterally from each other across the width of channel 124. A gasket 158 is disposed between inner frame member 114 and stair system 112. A bead of sealant material, or calking, 162 is placed in the channel 124 of inner frame member 114 and preferably between screws 160.

As indicated above, outer frame member 116 differs from outer frame member 16 in that it includes a living hinge 150 disposed in the region between legs 142 and 144, and does not include a second flange equivalent to flange 40 on outer frame member 16. Living hinge 150 is a narrower region that divides outer frame member 116 into two sections 116 a and 116 b which are movable relative to each other about hinge 150. Section 116 a has an inner edge 116 c that is opposed to an inner edge 116 d of section 116 b. Section 116 b has a rounded tip 141 instead of the second flange 40 of outer frame member 16. The installer is able to flex outer frame member 116 about living hinge 150 during installation of liner 154. This can be accomplished by holding outer frame member 116 between the thumb and forefinger of one hand and pushing inwardly. This movement opens a gap 151 between inner edges 116 c, 116 d and slightly reduces the distance between legs 142, 144. It is therefore easier to ease legs 142, 144 of outer frame member 116 into channel 124 of inner frame member 114. As legs 142, 144 slide into channel 124; they engage liner 154 and push the same inwardly into channel 124. This movement causes the bead of calking 162 to spread out in channel 124 and into grooves 128, 134 thereby bonding liner 154 to inner frame member 114. Tips 142 c, 144 c of legs 142, 144 slide into grooves 128, 134 and, as they do so, the gap 151 between inner edges 116 c, 116 d narrows until the outer surfaces of sections 116 a and 116 b are flush (FIG. 11). The outermost surface of sections 116 a and 116 b are represented in FIG. 11 as outer surface 116 e. At this stage, outer frame member 116 is interlockingly engaged with inner frame member 114 and liner 154 is clamped, wedged or retained thereinbetween. Outer frame member 116 will tend to stay in the closed position as hinge 150 is positioned below the longitudinal center of outer frame member 116 and when closed will move sections 116 a and 116 b to the over-center position. A hollow passageway 153 is created by the closure of gap 151. If it is necessary at some point to disengage outer frame member 116 from inner frame member 114, the installer may insert the head of a flathead screwdriver between the abutting inner edges 116 c, 116 d and into the passageway 153. The screwdriver can then be used as a lever to separate section 116 a from section 116 b.

FIGS. 12-15 show a variation of outer frame member 116, with the variation being generally indicated in these figures by the number 216. Outer frame member 216 is substantially identical to outer frame member 116 except that the inner edges 216 c, 216 d of sections 216 a, 216 b are provided with a locking mechanism. The locking mechanism comprises a latch member 270 that projects outwardly from the inner edge of one of sections 216 a, 216 b and a corresponding aperture 272 defined in the inner edge of the other of sections 216 a, 216 b. In the attached illustrations, latch member 270 extends outwardly from inner edge 216 d of section 216 b and the corresponding, complementary aperture 272 is defined in the inner edge 216 c of section 216 a.

As with the previous embodiments, inner frame member 214 is secured to stair system 212 and backer board 219, or some other fixture, by a plurality of screws 260. As with the previous version, pairs of screws 260 are utilized for this purpose at spaced intervals along the length of inner frame member 214. A gasket 258 is positioned between inner frame member 214 and recessed region 260 of stair system 212. Outer frame member 216 is used to force liner 258 into channel 224 of inner frame member 214 in much the same manner as in the previous embodiment. However, as outer frame member 216 is pushed inwardly to move legs 242, 244 and therefore the liner 258 into channel 214, the latch member 270 progressively enters the corresponding aperture 272 (FIGS. 12-14) until latch member 270 is entirely retained within aperture 272 (FIG. 15). At this point, sections 216 a and 216 b are latched together and cannot be accidentally dislodged. As with the previous version, sections 216 a, 216 b may be separated from each other by inserting the head of a flat head screwdriver between inner edges 216 c and 216 d and then using the screwdriver as a lever to separate sections 216 a and 216 b. The insertion of legs 242 and 242 tends to force liner 254 into channel 224 of inner frame member 214 and into contact with sealant 260. The sealant 260 spreads throughout channel 260 and into grooves 228, 234.

It will be understood that while the inner frame member has been disclosed as having an interior channel therein and the outer frame member has been disclosed as having a pair of spaced apart legs that are receivable within the channel, the legs may instead be provided on the inner frame member and the channel defined in the outer frame member without departing from the spirit of the present invention.

It should further be understood that the bead of sealant or calking that is placed in the channel in the inner frame member may be placed there by the manufacturer or may be placed there by an installer.

Furthermore, the embodiments of the invention illustrated in FIGS. 8-15 are shown as incorporating a living hinge 150 formed by molding a thinner region of plastic material than the remainder of the outer frame member. It should be understood that the outer frame member may, instead, be provided with an actual hinge that is mounted between the two sections 116 a and 116 b or 216 a and 216 b.

Referring to FIGS. 16-21 there is shown a third embodiment of a sealing member in accordance with the present invention and generally indicated at 310. The fixtures that are typically installed in pools using vinyl liners are made from plastic or fiberglass. As such, they are molded or cast from the plastic or fiberglass. In accordance with the present invention, sealing member 310 is molded or cast into smaller fixtures such as the drain 380 illustrated in these figures. In these instances, instead of utilizing an inner frame member and outer frame member that are designed to snap fit together, an outer portion of the frame of the fixture itself is designed to snap-fit with an inner portion of the frame. The liner is trapped therebetween in much the same way as was described with reference to the embodiments shown in FIGS. 1-15.

Drain 380 is therefore provided with a housing 382 molded to include an inner frame member 314. Inner frame member 314 is molded to include an annular channel 324 therein. An annular outer frame 316 is provided to snap-fittingly engage inner frame 314 and to retain a portion of liner 354 thereinbetween.

FIG. 21 shows outer frame member 316 including an annular ridge 382 positioned to be received in channel 324 of inner frame member 314. Ridge 384 preferably is of a shallower arc of curvature than is channel 324. A bead of calking or other sealant 362 is placed in channel 324 either during manufacture or by the installer during installation of the fixture Outer frame member 316 preferably includes a plurality of leg members 386 configured to lockingly engage in the complementary shaped and positioned recessed regions 388 on inner frame member 314. A cover 390 is mounted over outer frame member 316. Cover 390 is provided with a plurality of apertures 392 therein to allow water from the pool to flow into the interior 394 of housing 382 and subsequently out of the outlet 396 (FIG. 20) therein.

The drain 380 will be installed in an appropriate location in the pool prior to the installation of liner 354. Specifically, housing 380 is installed and is connected to a drainage system (not shown) via outlet 396. If necessary, the installer will apply the bead of calking 362 into channel 324 of lower frame member 314. The liner is then installed in the pool and will be drawn tightly across the opening to the interior 394 of housing 382. After the air has been evacuated from between liner 354 and the surface of the pool that it abuts, the installer will engage outer frame member 316 with inner frame member 314. This is accomplished by positioning outer frame member 316 over inner frame member 314 in such a manner that a portion of ridge 384 is received in channel 324 in inner frame member 314. As the ridge 384 enters channel 324 it forces a portion of liner 354 into calking 362. The calking 362 is spread throughout the entire channel 324 and the liner 354 becomes sealingly retained between inner and outer frame members 314, 316. When leg members 386 reach the appropriate locations, the tip 386 a of each leg member 386 slides under a complementary shoulder 388 a in recessed area 388 and thereby locks the frame members 314, 316 together.

The installer then uses a cutting tool to cut away the region of liner 354 that extends across the opening 316 a of outer frame member 316. Liner 354 is thereby provided with an opening 354 a through which water may flow. Cover 390 is then screwed into position over outer frame member 316.

The provision of this type of sealing member, comprised of an inner frame member molded to one part of a small fixture and an outer frame member molded to another part of the small fixture, may be utilized on any of the smaller fixtures or components that need to be sealingly mounted on a vinyl pool liner.

It will be understood that while FIGS. 3 and 7 show an inner frame member that is mechanically attachable to a stair system by way of a plurality of fasteners, the inner frame member may, instead, be integrally molded with the stair system in much the same manner as is disclosed with reference to the molding of the inner frame member 314 on the drain fixture illustrated in FIGS. 16-21.

None of the embodiments of the invention disclosed herein requires any type of elongated fastener, such as a screw, that will pierce the liner when it is being secured to the fixture. Instead, two complementary frame members are used to retain the liner between them in a manner that does not cause the liner to be pierced. The bead of calking or sealant ensures that there is an air-tight and water-tight seal between these components.

FIGS. 22-29 show another embodiment of a sealing member which is utilized to secure and seal a vinyl pool liner 454 around a stair system 412. This additional embodiment of the sealing member is generally indicated at 410. Stair system 412 includes a first side wall 412 a, a second side wall 412 b and a bottom wall 412 c. Sealing member 410 comprises a first sealing component 410 a which is disposed on first side wall 412 a, a second sealing component 410 b which is disposed on second side wall 412 b, and a bottom sealing component 410 c which is disposed on bottom wall 412 c. In accordance with a specific feature of the present invention, sealing component 410 further includes a first corner assembly 417 and a second corner assembly 419. First and second corner assemblies 417, 418 are installed on the pool wall 429 between the respective one of the first and second sealing components 410 a, 410 b and the bottom sealing component 410 c in the corner zones adjacent the bottom step of the stair system 412.

Each of first, second and bottom sealing components 410 a, 410 b, 410 c which make up sealing member 410 (FIG. 23) differ from the first, second and bottom sealing components 10 a, 10 b, 10 c, of sealing member 10 in a number of ways. Firstly, sealing member 410 differs from sealing member 10 in that when viewed from the front, the overall shape of first sealing component 410 a differs from that of first sealing component 10 a; the overall shape of second sealing component 410 b differs from that of second sealing component 10 b; and the overall shape of bottom sealing component 410 c differs from that of bottom sealing component 10 c. Specifically, each of the first and second sealing components 10 a, 10 b has an upper end disposed substantially at right angles to the sides thereof and a lower end that is mitered and is disposed generally at 45° to the sides thereof. Bottom sealing component 10 c has left and right ends that are mitered in opposite directions to each other and are complementary to the bottom ends of first and second sealing components 10 a, 10 b, respectively. Consequently, each of the left and right ends of bottom sealing component 10 c is disposed at 45° relative to the top and bottom edges thereof. It has been found that there is a tendency during installation for vinyl pool liners to pucker and fold into wrinkles in the corner zones adjacent the bottom step of the stair system. This is especially problematic since each corner zone may include three layers of vinyl that overlay each other. The wrinkling of the liner, the additional thickness of the vinyl combined with the sharp edges of the mitered ends of first, second and bottom sealing components 10 a, 10 b, 10 c, substantially increases the risk that the vinyl liner will be pierced or cut in these zones.

First sealing component 410 a differs in overall shape from first sealing component 10 a when viewed from the front in that both of its top and bottom ends 411 a, 411 c are disposed substantially at right angles to the sides 411 b thereof. Similarly, second sealing component 410 b differs in overall shape from second sealing component 10 b in that both of its top and bottom ends 411 a, 411 c are disposed substantially at right angles to the sides of 411 b thereof. Furthermore, bottom sealing component 410 c differs in overall shape from bottom sealing component 10 c in that the left and right ends 413 a, 413 b are both disposed at right angles to the top and bottom edges 413 c thereof. Additionally, bottom ends 411 c of both of first and second sealing components 410 a, 410 b are separated from the respective one of the left and right ends 413 a, 413 b of bottom sealing components 410 c both vertically and horizontally instead of contacting the same as is the case in sealing component 10. Thus, in sealing member 410, a right angled gap is defined between bottom end 411 c of first sealing component 410 a and left end 413 a; and between bottom end 411 c of second sealing component 410 b and right end 413 b. This gap is shown in FIG. 24. First corner assembly 417 is utilized to span the gap between bottom end 411 c of first sealing component 410 a and left end 413 a of bottom sealing component 410 c. Second corner assembly 419 is utilized to span the gap between end 411 c of second sealing component 410 a and right end 413 b of bottom sealing component 410 c.

In accordance with a specific feature of the present invention, first and second corner assemblies 417, 419 are curved to substantially prevent damage to vinyl pool liner 454 during installation, as will be hereinafter described. First and second corner assemblies 417, 419 are mirror images of each other and each is generally a curved “L” in overall shape when viewed from the front (FIG. 25). The radius of curvature is such that the risk of cutting liner 454 on the same is substantially minimized relative to previously known right-angled or mitered parts. First and second corner assemblies 417, 419 preferably are injection molded plastic parts, while first and second sealing components 410 a, 410 b and bottom sealing component 410 c are straight extruded plastic parts.

First corner assembly 417 will be described in further detail herein but it will be understood that the description thereof applies equally to second corner assembly 419. In accordance with the present invention and as may be seen from FIG. 24, first corner assembly 417 comprises an inner frame member 423, an outer frame member 425, and a cover 427 A strip 421 of double-sided adhesive tape 421 preferably is utilized to secure first corner assembly 417 to wall 429 of stair system 412. Each of strip 421, inner frame member 423, outer frame member 425, and cover 427 are substantially complementary in overall shape, i.e., they are all a generally rounded L-shape when viewed from the front. Strip 412 includes a first limb 421 a and a second limb 421 b that are disposed generally at right angles to each other and are separated by a curved region 421 c. Inner frame member 423 comprises a first limb 423 a and a second limb 423 b that are disposed generally at right angles to each other and are separated by a curved region 423 c. Outer frame member 425 comprises a first limb 425 a and a second limb 425 b that are disposed generally at right angles to each other and are separated by a curved region 425 c. Cover 427 comprises a first limb 427 a and a second limb 427 b that are disposed generally at right angles to each other and are separated by a curved region 427 c. Cover 427 further includes a first end region 435 a provided at the free end of first limb 427 a and a second end region 435 b provided at the free end of second limb 427 b. The cross-sectional dimensions of each of the first and second end regions 435 a, 435 b preferably are larger than the rest of cover 427.

Referring to FIG. 27, inner frame member 423 is generally U-shaped in cross-section and includes a base 423 d and upstanding first and second legs 423 e. Legs 423 e each terminate in inwardly extending shoulders 423 f. Base 423 d, legs 423 e and shoulders 423 f bound and define a channel 423 g.

Outer frame member 425 is also generally U-shaped in cross section and includes a base 425 d, downwardly extending first and second legs 425 e, and lips 425 f. Base 425 d, legs 425 e and lips 425 f bound and define a channel 425 g. Outer frame member 425 is smaller in width than inner frame member 423 and legs 425 e are configured to slide into channel 423 g of inner frame member 423 and lips 425 f are configured to snap-fittingly and interlockingly engage shoulders 423 f. This interlocking engagement will substantially prevent outer frame member 425 from disengaging from inner frame member 423. Outer frame member 425 further defines at least one and preferably a plurality of apertures 433 therein that are spaced at intervals along first and second limbs 425 a, 425 b and curved region 425 c. Each aperture 433 extends between the interior and exterior surfaces of outer frame member 425 and is disposed generally centrally between the legs 425 e. The purpose of apertures 433 will be described further herein.

Referring still to FIG. 27, cover 427 is also generally U-shaped in cross-section (FIG. 27) and is configured to be snap-fittingly engaged over outer frame member 425. Cover 427 includes a base 427 d and legs 427 e. At least one of legs 427 e terminates in a rounded tip 427 f. (Preferably, both of legs 427 e terminate in rounded tips 427 f) Base 427 d and legs 427 e bound and define a channel 427 g. Cover 427 further includes one or more connector studs 439 that extend outwardly from base 427 d and into channel 427 g. Studs 439 are complementary positioned to apertures 433 in outer frame member 425. Studs 430 are configured to be snap-fittingly engaged in apertures 433 in outer frame member 425 to retain cover 427 on outer frame member 425. Studs 439 are complementary in shape and size to apertures 433 and preferably include flanges 439 a, 439 b (FIG. 27) that are able to flex inwardly toward each other when inserted into aperture 433 and then flex outwardly again to lock onto base 425 d. Flanges 439 a, 439 b preferably have beveled exterior faces to make it easier to insert the same into aperture 433. It should be noted that the width of cover 427 as measured between legs 427 e is greater that the width of both of the inner frame member 423 and outer frame member 425 so that when inner and outer frame members 423, 425 are engaged and cover is further engaged therewith, legs 427 e extend beyond and overlap a substantial portion of legs 423 e of inner frame member 423 and extend downwardly toward wall 429. It should further be noted that when inner and outer frame members 423, 425 and cover 427 are so engaged, a gap 449 is defined between legs 427 e and leg 423 e.

Sealing member 410 of the present invention is used in the following manner. Sealing member 410 is applied in a recessed region 456 (FIG. 27) of pool wall 429. It is sometimes necessary for the installer to sand or otherwise remove small protrusions that are formed during manufacture of first and second sealing members 410 a, 410 b; bottom sealing component 410 c, and first and second corner assemblies 417, 419 prior to installation of the same. This is done to ensure that the protrusions do not accidentally pierce or cut pool liner 454 during installation. The various parts of sealing member 410 may be applied to stair system 412 in any order considered satisfactory to the installer.

The first step in the process is the securement of a strip of double-sided adhesive tape to the wall 429. The strip may be a single piece of double-sided tape that is die-cut to the exact shape of the entire sealing member 410 or it may be comprised of several individual shorter lengths of double-sided tape that are individually positioned beneath the first sealing component 410 a, second sealing component 410 b, bottom sealing component 410 c and first and second corner assemblies 417, 419. It is this last scenario that is described hereafter where the strip of double-sided adhesive tape is comprises of three strips 431 for securing the first, second and bottom sealing components 410 a, 410 b, 410 c; and two strips 421 for securing the first and second corner assemblies 417, 419. Strips 431 are substantially complementary in shape and size to the bases of the associated inner frame members 414 of first, second and bottom sealing components 410 a, 410 b, and 410 c. Strips 421 are substantially complementary in shape and size to the bases of first and second corner assemblies 417, 419. In each instance the strips of double-sided adhesive tape 431, 421 are pressed into a recessed region 456 (FIG. 26) of wall 429 surrounding stair system 412. It will be understood that strips 431, 421 preferably will each include a protective peelable paper layer over both of the interior and exterior surfaces thereof to stop the adherence of the same to other objects before its application to pool wall 429. Thus, no screws or other fasteners preferably are used to secure sealing member 410 to pool wall 429 although they may alternatively be used for this purpose. The strips 431, 421 may all be applied to wall 429 and then the respective inner frame members engaged therewith or they may be applied individually as each respective part of sealing member 410 is installed.

Once strips 431, 421 has been adhered to wall 429, the respective inner frame member 416, 423 is engaged therewith by pushing the inner frame member into contact with the adhesive outer side of the double-sided tape. It should be noted that sealing strip 421, inner frame member 423 and outer frame member 425 of first corner assembly 417 are configured to fit more or less exactly in the gap defined between bottom end 411 c of first sealing component 410 a and left end 413 a of bottom sealing component 410 c. When strip 421, inner frame member 423 and outer frame member 425 are installed in recessed region 456 (FIG. 26) of pool wall 429 then first end 425 h of outer frame member 425 is adjacent bottom end 411 c of first sealing component 410 a and second end 425 i of outer frame member 425 is adjacent left end 413 a of bottom sealing component 410 c. It will further be understood that the first end 423 h of inner frame member 423 is substantially aligned with first end 425 h; and that second end 423 i of inner frame member 423 is substantially aligned with second end 425 i. First ends 423 h, 425 h and bottom end 411 c form a first joining zone between first corner assembly 417 and first sealing component 410 a. Second ends 423 i, 425 i and left end 413 a form a second joining zone between first corner assembly 417 and bottom sealing component 410 c.

An edge region of liner 454 is then placed across the outer surfaces of the various inner frame members 414, 423 installed on wall 429 and the respective outer frame members 416, 425 are snap-fittingly engaged therewith. Thus, the edge region of liner 454 is forced into the channels, such as channel 423 g, of the inner frame members 414, 423 and is clamped between inner and outer frame members 423, 425.

Finally, cover 427 is snap-fitted onto outer frame members 425 of first and second corner assemblies 417, 419 by pushing studs 439 on cover 427 through apertures 433 in outer frame members 425. It should be noted that when cover 427 is in place on outer frame member 425, ends 435 a, 435 b of cover 427 extend over the first and second joining zones and overlap portions of the outer frame members 416 of each of first and bottom sealing components 410 a, 410 c. This aids in ensuring that the outer frame member 425 will not easily disengage from inner frame member 423. As is readily seen in FIGS. 27-29, cover 427 has a gentle cross-sectional curvature that positions the legs 427 e thereof a distance outwardly from the legs 423 e of inner frame member 423. Additionally, the rounded tip(s) 427 f of cover 427 help to ensure that any contact the tip(s) 427 f may have with pool liner 454 does not result in liner 454 being inadvertently cut thereby.

If liner 454 is later to be replaced, cover 427 is disengaged by inserting an end of a flat-head screwdriver, for instance, under one of the end regions 435 a, 435 b of cover 427 and prying the same off outer frame member 425. Outer frame member 425 is then detached in a similar fashion from inner frame member 423, the old vinyl pool liner 454 is removed and a new one (not shown) is positioned over inner frame member 423. Outer frame member 425 is snap-fittingly engaged with inner frame member 423 and the cover 427 is then re-engaged with outer frame member 425.

FIGS. 28 and 29 also show that a bead of silicone sealant 441 may be introduced into channel 423 g of inner frame member 423 prior to the introduction of the edge section of vinyl pool liner 454 across inner frame member 423 and the subsequent engagement of outer frame member 425 therewith. FIG. 29 shows that silicone sealant 441 engages the interior surface of vinyl pool liner 454 and sealingly retains the same within channel 423 g of inner frame member 423. Liner 454 preferably is also trimmed before cover 427 is snap-fittingly engaged with outer frame member 425. Thus, end 454 a of liner 454 is not visible when cover 427 is engaged with outer frame member 425, giving the stair system 412 a finished and aesthetically appealing appearance.

While it has been disclosed that outer frame member 425 of first corner assembly 417 includes a plurality of apertures 433 therein and outer cover includes complementary studs 439 that are engaged in those apertures 433, it will be understood that, alternatively, the apertures may be defined in the interior surface of the cover and complementary studs may be provided on the exterior surface of the outer frame member, without departing from the scope of the present invention. More particularly, the apertures in the cover may be blind apertures that are not visible when the cover is engaged with the outer frame member.

It should be understood that first, second and bottom sealing components 10 a, 10 b, 10 c, 410 a, 410 b, 410 c may be differently configured from the structures shown in FIGS. 1 through 29 in that they may also include covers (not shown) which engage the outer frame members thereof. If this is the case, then the configuration of the respective outer frame members will be changed so as to be able to matingly engage that cover. This may be done by inclusion of the cooperating apertures and studs disclosed herein.

It should be understood furthermore, that any suitable means of securing cover 427 to outer frame member 425 other than the cooperating studs 439 and apertures 433 may also be utilized without departing from the scope of the present invention.

It will further be understood that while first and second corner assemblies 417, 419 have been disclosed as having two limbs that are disposed at 90° relative to each other, any other desired configuration, shape or angled assembly may be manufactured to suit any specific or unique configuration of pool fixture to which the pool cover needs to be secured. Furthermore, a cover may be engaged with these uniquely configured inner and outer frame members to prevent the outer frame member from accidentally disengaging from inner frame member. This disengagement could occur, as in the previously described corner zones, because of stresses placed in a particular region of the liner by virtue of the shape of the fixture it must be secured to.

It will further be understood that while the outer frame member 425 has been illustrated as being engageable with the inner frame member 423 such that the legs 425 e thereof are received within the channel 423 g; the outer and inner frame members may be differently configured so that the legs of the inner frame member are receivable within a channel defined by the base and legs of the outer frame member. The liner 454 would still be clampingly retained between the differently configured inner and outer frame members as described above and the cover will also remain releasably engageable with the reconfigured outer frame member.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
